This lesson aligns with the Early Stage 1 Science outcomes and content descriptions from the NSW Science K-6 syllabus:

Outcome:

• Students describe observable features of living things and how they behave (ENe-2A).

Content Focus:

• Living World: The school environment and local habitats (Science K-6, Early Stage 1).
• Skills: Observing, asking questions, representing observations and ideas, communicating findings.

Skills Development:

• ENe-4A: Observing, asking questions, and gathering information to develop ideas.
• ENe-5B: Using drawings and simple tables to represent observations and ideas.
• ENe-6B: Communicating observations and ideas in a variety of ways.

By engaging with a worm farm, students explore living things, their environments, and their roles in decomposition and the ecosystem.

WALT (We Are Learning To):

• Observe living creatures closely and describe what we see.
• Ask questions about how a worm farm works and what worms do.
• Collect and communicate simple data about worms using drawings and talking.
• Understand that worms help recycle food waste into healthy soil.

---

Success Criteria:

• I can look closely at worms and describe their features.
• I can ask questions about worms and their environment.
• I can draw or tell about what I see happening inside the worm farm.
• I can share my ideas about why worms are important for the garden.

---

Materials Needed:

• A small classroom worm farm setup or clear container with a worm farm kit (including worms, soil, food scraps).
• Magnifying glasses for close observation (1 per 2 students).
• Printable observation sheets with spaces for drawing worms and simple tables for 'What I see' and 'What I wonder' columns.
• Whiteboard or chart paper for group discussion.
• Pencils, crayons or coloured pencils.
• Hand wipes or small towels for cleaning hands after observation.

Lesson Outline:

1. Introduction (10 minutes)

• Gather the students on the floor around the worm farm.
• Show the worm farm container and ask simple questions: "What do you think lives inside this farm? What do worms eat?"
• Explain briefly how worms help turn food scraps into healthy soil.
• Introduce the WALT and success criteria clearly.

2. Observation Activity (15 minutes)

• Break students into pairs.
• Give each pair a magnifying glass and an observation sheet.
• Guide students to look carefully at the worms, their movements, the soil, and the food scraps.
• Support students to draw what they see on their sheets.
• Encourage students to write or dictate one or two questions about worms or the farm to the teacher or an aide.
• Walk around, prompting with questions:
  • "How many worms can you see?"
  • "Are the worms moving? How?"
  • "What do you think worms do in the soil?"

3. Sharing and Communicating (10 minutes)

• Regroup as a class.
• Invite volunteers to share their drawings and ask their questions aloud.
• Chart all the student questions and ideas on a large poster.
• Use simple scientific vocabulary such as worm, soil, food scraps, recycle, healthy soil.
• If any questions can be answered simply, do so; else, note them for future exploration.

4. Simple Data Collection (5 minutes)

• On the whiteboard/chart paper, create a simple tally chart:
  • For example: Number of worms seen by each pair.
• Invite each pair to share their worm count and help mark tallies.
• Count and find the total number of worms observed together.
• Discuss the importance of counting and observing carefully.

5. Conclusion and Reflection (5 minutes)

• Recap what was learned about worms and worm farms.
• Restate the WALT and ask students if they think they met the success criteria.
• Prompt students to think about ways they can help worms when they go home (e.g., throwing food scraps in a compost bin).
• Remind students to wash hands after handling worm farm materials.

---

Assessment Ideas:

• Observe student participation in discussion and observation.
• Review students’ drawings and questions for understanding of worm features and curiosity.
• Informally assess ability to communicate observations verbally and through drawings.
• Check for engagement with data collection (tally marks) and willingness to share.
• Use anecdotal notes to record individual student’s scientific questioning and communicative skills.

---

Extension Ideas (for earlier/later times or home learning):

• Create a class worm storyboard showing the life cycle of a worm.
• Plant a small garden patch using soil enriched by worm castings.
• Start a compost bin and observe decomposition alongside the worm farm.
• Use simple videos or pictures to show worms in other environments.

By adhering to the NSW Early Stage 1 Science syllabus, this lesson encourages young learners to observe real-world biological phenomena, engage in natural questioning, communicate findings simply, and appreciate the natural process of recycling nutrients in the ecosystem through worms. It fosters curiosity and foundational scientific literacy through hands-on interaction, suited for Kindergarten students' development and cognitive level.

This lesson plan is practical, inclusive, and aligns explicitly with NSW curriculum expectations for Kindergarten Science learning about living things and their environments.
